Assessments of the pharmacological profiles of antipsychotic agents have shown that the serotonin receptor family is often involved in their pharmacodynamics. Response to antipsychotic therapy is highly variable, yet prognostic biomarkers are lacking. The aim of the study was to investigate the association of 14 single nucleotide polymorphisms (SNPs) selected from HTR3C, HTR3D, HTR5A and HTR6 with risperidone response in 201 Han Chinese schizophrenia patients. The results showed that the HTR6 rs6699866 was significantly associated with risperidone response and predicted greater positive symptom reduction in risperidone-treated subjects (P = 0.04 and 0.004, respectively). The current study provides insight into the relationship between genetic polymorphisms in serotonin receptor family and risperidone therapeutic response in Han Chinese population. To clarify the role of these SNPs in clinical response to antipsychotic medication, and risperidone in particular, the study warrants further investigation in larger well-characterized samples.

Drugs that bind to but do not activate SEROTONIN 5-HT2 RECEPTORS, thereby blocking the actions of SEROTONIN or SEROTONIN 5-HT2 RECEPTOR AGONISTS. Included under this heading are antagonists for one or more specific 5-HT2 receptor subtypes.
Drugs that bind to but do not activate SEROTONIN 5-HT3 RECEPTORS, thereby blocking the actions of SEROTONIN or SEROTONIN 5-HT3 RECEPTOR AGONISTS.
Drugs that bind to but do not activate SEROTONIN 5-HT4 RECEPTORS, thereby blocking the actions of SEROTONIN or SEROTONIN RECEPTOR AGONISTS.
A serotonin receptor subtype found distributed through the CENTRAL NERVOUS SYSTEM where they are involved in neuroendocrine regulation of ACTH secretion. The fact that this serotonin receptor subtype is particularly sensitive to SEROTONIN AGONISTS such as BUSPIRONE suggests its role in the modulation of ANXIETY and DEPRESSION.
A serotonin receptor subtype found primarily in the CENTRAL NERVOUS SYSTEM and the CHOROID PLEXUS. This receptor subtype is believed to mediate the anorectic action of SEROTONIN, while selective antagonists of the 5-HT2C receptor appear to induce ANXIETY. Several isoforms of this receptor subtype exist, due to adenine deaminase editing of the receptor mRNA.
